A Yantra is an instrument, or a talisman or a mystical diagram usually in silver or copper. It is a technique or path, considered the simplest and shortest, through which one can attain one's desires, and fulfill one's wishes. It is said that the 'Devas' (Gods) or Deities (Goddess) reside in the Yantras and by performing 'Puja' or worship of Yantras, one can appease the Deities, remove the malefic effects of planets, and increase the flow of positive influences.
